Definitions

  • This invention is directed to an improved closure for a carton.
  • the invention is directed to a container pour closure for a carton board box container.
  • carton closures in the prior art that function to selectively close off a carton container dispensing opening.
  • carton containers are box-shaped and hold dry granular materials which flow freely through the dispensing opening.
  • Such materials may include laundry detergent or the like.
  • the container opening is located on the side wall near its top or actually in the top.
  • Some prior art containers include a pour spout which is actually a separate piece from the carton board container.
  • the spout thus described may be made of metal material such as aluminum. It is ramp-shaped and is movably fitted into the dispensing opening in the side of the container, and may be articulated from a closed position, where it is in the same plane as the container side wall, to an opened position where it forms a pour spout.
  • a disadvantage of this prior art structure is that it requires an extra manufacturing step and additional non-carton board material. This all adds to unwanted cost.
  • the invention takes the form of a closure flap for carton board containers or the like which is an extension of the top flap, thereby eliminating an additional panel.
  • a dispensing opening is diecut in an end wall of the container, which forms a plug for the opening. This plug is glued to the closure flap so that it comes away with and is a functional part of the closure flap.
  • a locking tab extends from the closure flap and is spot glued to the end wall when the container is initially filled. By grasping and pulling away the tab from the end wall, the closure is initially opened. Score lines on the closure flap enable the plug to be re-inserted and sealed within the dispensing opening while at the same time locking the closure by means of the tab being located within the interior of the container.
  • FIG. 1 is a top quarter isometric view of the upper portion of a carton or box container illustrating the closure of the instant invention in the fully closed position;
  • FIG. 2 is a similar view illustrating the closure in the opened condition or position so as to provide a dispensing opening
  • FIG. 3 is an enlarged fragmentary elevation view taken in the direction 3--3 in FIG. 1;
  • FIG. 4 is a view similar to FIG. 3 showing the locking tab fully engaged
  • FIG. 5 is an enlarged fragmentary sectional view in a plane taken along the lines 5--5 in FIG. 1;
  • FIG. 6 is a view similar to FIG. 5 showing the closure flap being articulated away from the dispensing opening;
  • FIG. 7 is a similar view but showing the closure bent along a score line so that it may be inserted into the dispensing opening for locking;
  • FIG. 8 is a similar view showing the closure fully engaged in the opening with the locking tab securing it therein;
  • FIG. 9 is a fragmentary top plan view of the blank from which the carton is formed.
  • FIG. 10 is a view similar to FIG. 9 showing an alternate embodiment of the blank.
  • FIG. 1 a preferred embodiment of the invention in the form of a carton or box container 10.
  • Side panel or wall 12 joins with top flap 14 and end wall 16 to make up the container corner shown.
  • a closure flap 18 is an extension of top flap 14 and bends downwardly at score line 20. In this manner, closure flap 18 is in close sealing contact with end wall 16 when the closure flap is in the closed condition, as will be more fully described hereinafter.
  • the foldable blank may be made of flexible sheet material such as carton board.
  • Blank 22 includes a pair of side walls 12, 24 and a pair of end walls 16, 26.
  • End wall 26 is integrally joined to side wall 12 along scored fold line 28.
  • end wall 16 is integrally joined to side walls 16 and 24 at fold lines 30, 32, respectively.
  • a glue flap 34 is integrally joined to side wall 24 at fold line 36.
  • Top and bottom end flaps 38, 40 are integrally joined to end wall 26 along top and bottom fold lines 42, 44, respectively.
  • top flap 14 and bottom flap 46 are joined to side wall 12 along top and bottom fold lines 42, 44, respectively.
  • bottom end flap 48 is joined to end wall 16 at bottom fold line 44.
  • top glue flap 50 and bottom glue flap 52 are integrally joined to side wall 24 along top fold lines 42, 44, respectively.
  • closure flap 18 is integrally connected to top flap 14.
  • Blank 22 is formed into generally tubular shape as a first step in forming the box container.
  • Glue flap 34 is then adhered to the back or inner side of end wall 26 by means of a suitable adhesive.
  • Top end flap 38 is then bent at right angles to the plane of end wall 26.
  • bottom end flap 48 is also so bent.
  • Bottom glue flap 52 is then bent to right angles with respect to the plane of side wall 24 and so as to be in contact with bottom end flaps 40, 48.
  • Bottom end flap 46 is then bent along fold lines 44 until it contacts bottom glue flap 52.
  • a suitable adhesive is used to secure bottom flap 46 to bottom glue flap 52.
  • Top end flap 38 is then bent to be at a right angle to end wall 26.
  • Top glue flap 50 is also so bent to be at a right angle to side wall 24 along fold line 42. An adhesive is applied and top flap 14 bent so as to contact and adhere to top glue flap 50.
  • a generally square plug 54 has been prescored near but not immediately adjacent top fold line 42 on end wall 16.
  • Plug 54 is also spaced from fold lines 30 and 32.
  • Line 56 is cut clear through the end wall 16 while the other sides of plug 54 are perforated so that plug 54 remains in place until opened for dispensing.
  • Adhesive is placed on plug 54 as well as within an area 58 outside and below the plug 54.
  • Closure flap 18 is then bent along fold line 20 to contact side wall 16 including plug 54 and area 58. In this manner, closure flap 18 is adhered to plug 54 and to end wall 16 in the spot of area 58, as well as in the area on end wall 16 between score line 76 and top flap 14.
  • closure flap 18 may be slightly narrower than the width of end wall 16. Its side edges 60, 62 are spaced, not necessarily symmetrically, from the corners formed by fold lines 30, 32. Closure flap 18 also has a bottom edge 64 which is perpendicular to side edges 60, 62 and parallel to fold line 20. The closure flap is cut so as to produce a depending locking tab 66.
  • the locking tab 66 may be of any convenient shape, such as semi-circular, square, rectangular, etc. Cut lines 68, 70, which are extensions of the curve of tab 66, extend part way into closure flap 18 and have their uppermost extensions joined by a score line 72. As seen in this figure and in FIGS. 2 and 3, score line 72 is approximately in line with the lower edge 74 of plug 54.
  • FIG. 4 shows the locking tab 66 in the fully locked position or condition.
  • FIGS. 5-8 the steps in going from the initial to the fully closed and locked condition are illustrated.
  • tab 66 is first grasped and pulled away from end wall 16, breaking the small amount of adhesive in the area 58 shown in FIG. 9.
  • Plug 54 will be thereby pulled out of its sealing position and come away with closure flap 18.
  • FIG. 6 illustrates a continuation of this process, which creates a dispensing opening 80 in side wall 16 suitable for dispensing the granular product contained in the container.
  • closure flap 18 After dispensing, the closure is bent at score line 72 and inserted into opening 80, as seen in FIG. 7. Tab 66 is then inserted into the opening so that it contacts and rides against lower edge 82 of opening 80. By manual pressing on closure flap 18, plug 54 will be re-sealed into opening 80 while at the same time locking tab 66 will be positioned within the container as shown in FIGS. 4 and 8. For further dispensing, closure flap 18 is merely grasped and pulled away from wall 16 and locking tab 66 will be disengaged.
  • FIG. 10 An alternate embodiment of the invention is shown in FIG. 10, wherein structure corresponding to the first embodiment is designated by a prime.
  • a top minor end flap 49 is connected to end wall 16'.
  • Top minor end flap 49 is formed by means of cut lines 51, 53, 55, 57 in the blank. The presence of this top minor closing flap 49 enhances carton sealing and product containment.
  • Closure flap 18' is located slightly asymmetric with respect to top flap 14'. Parenthetically, top minor end 49 is bent at a right angle to end wall 16' and is glued between top flap 14' and top glue flap 50' in like manner to and at the same time as top end flap 38'.
  • Plug 54' is correspondingly asymmetrically located.
  • tab 66' is of generally rectangular shape as opposed to the generally semi-circular shape of the tab of the first embodiment.
